The Florida State board of trustees voted unanimously Friday to sue the ACC to challenge the legality of the league’s grant of rights and its $130 million withdrawal fee, a necessary first step to plot the school’s future and potential exit from the conference.

The 38-page lawsuit, filed in Leon County Circuit Court in Tallahassee, Florida, seeks a declaratory judgment against the ACC to void the grant of rights and withdrawal fee as “unreasonable restraints of trade in the state of Florida and not enforceable in their entirety against Florida State.”

The university alleges “chronic fiduciary mismanagement and bad faith” in the way the ACC has handled its multimedia rights agreements and undermined its members’ revenue opportunities. Florida State is also accusing the ACC of breach of contract and failure to perform.

“I believe this board has been left no choice but to challenge the legitimacy of the ACC grant of rights and its severe withdrawal penalties,” board chair Peter Collins said. “None of us like being in this position. However, I believe that we have exhausted all possible remedies within the conference and we must do what we believe is best for Florida State not only in the short term but in the long term.”

Florida State is now in unprecedented territory. No school has ever challenged a grant of rights in court.

ACC officials have previously used the word “ironclad” to describe the document, and that has been the operating assumption from leagues across the country — believing the language in the document is so rigid it would prevent schools from leaving. But because no school has ever challenged the document in court, nobody actually knows whether it is, indeed, as ironclad as described.

ACC commissioner Jim Phillips and Virginia president Jim Ryan, chair of the ACC board of directors, lamented Florida State’s “unprecedented and overreaching approach” in a statement.

“Florida State’s decision to file action against the Conference is in direct conflict with their longstanding obligations and is a clear violation of their legal commitments to the other members of the Conference,” the statement said. “All ACC members, including Florida State, willingly and knowingly re-signed the current Grant of Rights in 2016, which is wholly enforceable and binding through 2036. Each university has benefited from this agreement, receiving millions of dollars in revenue and neither Florida State nor any other institution, has ever challenged its legitimacy.”

The ACC also made a preemptive legal maneuver Thursday by filing a complaint for declaratory judgment against the Florida State board of trustees in state court in Mecklenburg County, North Carolina.
